How to do it

  1. 01

    Position your body on the floor in the basic sit-up position; knees to a ninety degree angle with feet flat on the floor and arms either crossed over your chest or to the sides. This will be your starting position.

  2. 02

    As you strongly tighten your glutes and hamstrings, fill your lungs with air and in a slow (three to six second count) ascent, slowly exhale. Tip: It is important to tighten the glutes and hamstrings as this will cause the hip flexors to be inactivated in a process called reciprocal inhibition, which basically means that opposite muscles to the contracted ones will relax.

  3. 03

    As you inhale, slowly go back in a controlled manner to the starting position.

  4. 04

    Repeat for the recommended amount of repetitions.

In the app

Janda Sit-Up needs no kit, so it appears whenever the day's window has room for it. Its minutes come from Rule 2 (Sessions are built to fit, never guaranteed, graded product): the window sets how long it runs, never the other way round.

If a machine is taken the engine swaps a same-pattern movement and says why.

Same pattern, with kit

Same movement pattern, same primary muscles — swap by what you have.
